To celebrate its 160th anniversary, Tissot reached back into its past and decided to bring back an iconic anniversary watch, the Tissot Heritage Navigator. The first version of this watch was released in 1953 when the brand turned 100, and now Tissot has updated the classic worldtimer design to suit the brand's modern identity, giving us the Heritage Navigator 160th Anniversary.

The biggest difference you'll notice immediately is the larger size for the 160th Anniversary Navigator. The 1953 centenary edition was 36mm, which was relatively large for the time, and accordingly the new Heritage Navigator is 43mm. The case is certainly large, but it wears very easy on the wrist. Plus, the increased size seriously helps legibility which is often a problem with true worldtime watches like this.

To make the Heritage Navigator easy to read, Tissot uses 12-hour markings on the bezel for reading the main time and 24-hour markings on the dial to help read the worldtime disk. Both black and silver dials are available with the steel case, and the black in particular offers a distinctly modern take on what is one of the most classic complications out there.

Through the sapphire caseback you can see the ETA 2893 worldtimer movement, with a Tissot-decorated winding rotor. The movement is a COSC-certified chronometer, like in many of Tissot's higher-end offerings.

In addition to the steel models, there is a special limited edition Heritage Navigator available in gold to further recall the original from 60 years ago. If you ignore the larger case size, this limited edition looks every bit the part of a 1950s travel watch. Only 333 pieces will be produced for the anniversary.

The Heritage Navigator 160th Anniversary is priced at $1,650 in steel (for both silver and black dials) and $8,250 for the solid 18k gold limited edition. To find out more, visit Tissot online.

This week's Bring a Loupe will mix tool watches and elegant pieces, introducing you to some of the shining stars in each category. You will learn about one of the rarest military watches, the Tornek-Rayville, and discover the Cosmic from Omega as well as another triple date moonphase calendar from Universal Geneve. As usual, you should expect a fair number of beautiful chronographs, including the inonic Lange Datograph. And I will also mention some auction picks, from a very sexy Patek to a disturbingly fraudulent Omega. This is your Bring a Loupe for July 31, 2015.

The Longines Heritage Diver Chronograph is a sturdy, boldly styled combo diver's watch and chronograph that takes inspiration from a great classic model. Is it just another me-too heritage model, or a real blast from the past? Find out now on The Value Proposition.

If you’re anything like me, you mainly know Zenith for their El Primero Chronographs—and, most notably, for their El Primero Classic Chronograph that they released at Baselworld this year. What most people don’t know is that the 150-year-old manufacture released another batch of watches at Baselworld 2015; these pieces received less camera-time than others, but they’re all doing pretty interesting things—so it may be unfair that Zenith’s new Type 20 Pilot collection has been flying under the radar for this long.

There are several reasons that most people should never consider bidding on a watch that has the words “as is” or “for repair” in its description on eBay. In addition to making me have to overpay for adventurous restorations, pieces like this trade at such a small discount that it is rarely, if ever, a cost effective way to get your hands on a great vintage piece. There are exceptions, but for the most part, for collectors this is a losing gamble. This recent adventure very well illustrates this point and shows off awesome vintage Tudor in the process.

HODINKEE Executive Editor Benjamin Clymer and CEO Kevin Rose are delighted to announce that Mr. Frank Roda has joined the HODINKEE team as our new Director of Business Development. In his new role, Frank will oversee advertising and strategic partnerships.

This year at BaselWorld, Glashütte Original announced two new versions of the PanoMaticLunar, equipped with two new dial colors, and we just had our first chance to go hands on and close up with both watches. The two new versions are a steel PanoMaticLunar with a blue dial, and a rose gold model with a black dial.

Recently, HODINKEE reader Brandon Moore sent in a question: "I am wondering if the modern interpretations of the Breguet Natural Escapement (F.P. Journe Optimum, Kari Voutilainen Vingt-8, and Laurent Ferrier Automatic) have implemented specific solutions to the shortcomings of this design, namely the 'backlash' between the escape wheels, that Breguet experienced, and which caused him to ultimately abandon his design." This is a wonderful question, that deserves a careful response.

The Speedmaster Professional has, since its introduction in 1957, come in a truly bewildering variety of shapes, sizes, designations and limited editions, but one of the most polarizing models, when it appeared, was the X-33. The X-33 was introduced, in the first version, in 1998; it was the result of an Omega development program designed to (finally) produce a multifunction quartz watch that would be a completely modern successor to the mechanical Speedmaster Professional, and that would meet up to date NASA and ESA requirements for a flight-qualified timepiece. It was an ambitious project, which took place over the course of five years. Prototypes were flight-tested by both American and European astronauts; the first version of the X-33 would go on to be used by U.S., European, and Soviet astronauts on the Space Shuttle, the Mir Space Station, and other missions and it was used by military flight crews as well.

Hamilton's film What Makes a Fine Watch Fine opens with a shot of a transparent watch, its gear train seemingly floating in air. Today we are used to seeing brands advertise their new watches with computer rendered animations that show the mechanics of a watch movement in amazing clarity. The absolutely crazy thing about that film, and the watch that it shows, is that it was shot in 1947.
